年轻洋底测年Ｄ．Ｍ．Ｃｈｒｉｓｔｉｅ尽管火山熔岩空间分布令人满意且能大量取样，但是，由于缺乏其样品直接、准确的年龄数据，对洋中脊火山岩石学及其演变的详尽研究长期以来受阻。即使这些特定区域内通过潜艇观测或遥控摄像一录相技术得到的地质图都能够对熔岩流体积... Young ocean floor dating D. M. Christie Despite the satisfactory spatial distribution of volcanic lavas and their ability to sample in large quantities, the exhaustive study of the mid-oceanic ridge volcanology and its evolution has been hampered by the lack of direct and accurate age data on its samples. Even if the geological map obtained by submarine observation or remote photography-video recording technology in these specific areas can get the ...
